Her father, Ismail, told local US media she had become angry because YouTube had stopped paying her for uploading videos.

The platform "stopped everything and now she has no income," he told NBC news.

He also said she had been reported missing on Monday after not answering calls for two days. Police later found her sleeping in her car in Mountain View, 25km (15 miles) south of the YouTube offices in San Bruno and reported this to her family, but did not detain her.

Aghdam's father then warned police that she might go to YouTube as she "hated the company," local media said.

YouTube terminated all of her channels following the shooting. Her Instagram and Facebook accounts have also been removed.

Aghdam also posted on her website about animal rights and the cruelty of the fur trade.
